Operator Input and Visualization

  • Touch area: The analog-resistive surface selects configured screen objects and data-entry fields.
  • Function keys: Eight physical keys call the functions assigned in the runtime project.
  • Display path: The TFT panel renders 800 x 480 images with 65,536 available colors.
  • Backlight: Brightness is dimmable and service planning follows the documented operating-hour value.

Controller Communication Path

  • Shared interface: One RS422/RS485 connection carries the selected fieldbus protocol.
  • Bus settings: Address and transmission rate must match the PLC and WinCC hardware configuration.
  • Termination: The panel position on the segment determines whether bus termination is enabled.
  • Diagnosis: Connector wiring, cable shield, network state, and configured connection are checked together.

Runtime Memory and USB Use

  • User memory: The 10 MB memory holds the compiled runtime project and its configured objects.
  • Alarm scope: Alarm texts and event definitions remain part of the transferred project.
  • Recipe data: Configured recipes use the panel memory and supported export or restore path.
  • USB media: The host port accepts supported storage for backup and documented transfer procedures.

Front Seal and Cabinet Conditions

  • Cutout: The enclosure opening follows the documented panel cutout dimensions.
  • Front seal: Uniform clamping pressure is required to achieve the IP65 front rating.
  • Rear space: The IP20 rear remains inside the cabinet with ventilation and cable clearance.
  • Orientation: Landscape, portrait, and inclined mounting use their respective temperature limits.
Description
Siemens 6AV2123-2GA03-0AX0 is a SIMATIC HMI KTP700 Basic DP panel that combines a 7-inch widescreen display, analog-resistive touch input, and eight physical function keys. It presents machine images, alarms, recipes, and process values configured in WinCC Basic.

Controller communication on 6AV2123-2GA03-0AX0 uses its shared RS422/RS485 connection for PROFIBUS DP, MPI, or supported Modbus RTU settings. The configured bus address, rate, connector, and termination must agree with the PLC network.

The 24 V DC input powers 6AV2123-2GA03-0AX0, while its USB host connection transfers supported backup or project data to external storage. Ten megabytes of user memory hold the runtime project, languages, alarm definitions, and recipes inside the panel.

When installed in the cabinet cutout, 6AV2123-2GA03-0AX0 provides IP65 protection at the front and IP20 at the rear. Mounting orientation and inclination determine which documented ambient-temperature limit applies.

Why does 6AV2123-2GA03-0AX0 show the project but not communicate with the PLC?
Check the 6AV2123-2GA03-0AX0 bus address, transmission rate, protocol, connector wiring, termination, PLC station, and WinCC connection.
What should be backed up before replacing 6AV2123-2GA03-0AX0?
Save the 6AV2123-2GA03-0AX0 WinCC source project, panel backup, communication settings, recipes, user data, passwords, and current panel image.
Why is touch input inaccurate on 6AV2123-2GA03-0AX0?
Clean the 6AV2123-2GA03-0AX0 surface correctly, run touch calibration, inspect the overlay, and check that cabinet clamping is not distorting the front.
Can the USB port of 6AV2123-2GA03-0AX0 replace its PLC interface?
No. The 6AV2123-2GA03-0AX0 USB host is for supported storage and service tasks; controller communication uses the configured RS422/RS485 fieldbus.
Why does 6AV2123-2GA03-0AX0 restart when the backlight turns on?
Measure the 6AV2123-2GA03-0AX0 24 V DC supply, startup drop, polarity, terminal seating, cable resistance, and source capacity.
Does the IP65 rating of 6AV2123-2GA03-0AX0 apply to the rear?
No. 6AV2123-2GA03-0AX0 provides IP65 at the correctly installed front, while the IP20 rear must remain protected inside the enclosure.
